The Mildred Lake Extension project (MLX) will sustain Syncrude’s current production levels by extending the life of their North Mine. Syncrude’s Mildred Lake Extension (MLX) project is located approximately 40 kilometres north of Fort McMurray within Township 093 and 094, Range 12, W4M in the Rural Municipality of Wood Buffalo, Alberta.

The project consists of two mine sites – MLX West (MLX-W), located northwest of the current North Mine and west of the MacKay River; and MLX East (MLX-E), located on the east side of the Mildred Lake Settling Basin.

The MLX West, West Access Road (MLX-W-WAR) project is one of a series of projects to support the development of the MLX-W mine to first ore in 2024. The MLX-W mine is essential; it provides continuity of oil sand feed supply to the plant. It overlaps with remaining ore from the North Mine resource and the future MLX-E or Aurora South. The planned MLX-W-WAR follows a 10-kilometre alignment that begins at a point on the Aostra Road, a short distance south of the Suncor access gate, and proceeds in a generally north-easterly direction into the MLX area.

The proposed MLX-W-WAR will provide an all-weather graveled road that can be used to facilitate movement of personnel, equipment and materials for the development of the MLX site in preparation for the commencement of mining activities.

Allnorth was engaged to provide the field assessments and engineering services required for the design and construction of approximately 10.4 kilometres of roadway and a 400m x 200m laydown area.

The proposed alignment was on undisturbed crown land. Allnorth completed the field investigations, approvals, permits, design and detailed designs, volume calculations and cost estimates, and tender preparation on behalf of the client.
